Open the Niagara System Asset(5.3+) in the attached file, Compile, and you'll see the comiler error.
Inside the if block, if I set the 4 components of the linear color together, there won't be a problem, or, if I set it separately but disconnect the input and use a constant value, there won't be a problem too.
